This invention relates to planlzing or felting machinery for use in themanufacture of fur and Wool hat bodies.

The chief object of the present invention is to provide machinery of theclass above described whereby, in practice, the bearings which go toform parts of the same are of improved construction and arrangement, canbe changed or removed at frequent intervals, and this more readily,cheaply and expeditiously than heretofore, and are made of such materialand form that they bear upon the shafting, more particularly of therollers of the machine, more evenly than is at present the case and keepsuch shafting in true alignment at all times.

According to this invention, the machine is provided with preferably a.plurality of shaft bearings, more particularly for the shafting of therollers of the machine, each of the said bearings comprising adetachable bush, sleeve or the like adapted to be prevented fromrotating relative to a housing therefor by means of a detachable capassociated With the said housing, the. said bush, sleeve or the likehaving a lug or projection or more than one lug or projection adapted toco-operate with an opening or hole or more than one opening or hole inthe detachable cap, or vice versa.

In order that the said invention may be clearly understood and readilycarried into effect the same Will noW be described more fully, by Way ofexample, with reference to the accompanying drawings, in Whichz- Figurel is a fragmentary end elevation of a planking or felting machineembodying the invention,

Figure 2 is a fragmentary longitudinal sectional vievv taken on the line-m of Figure l,

Figure 3 is a fragmentary transverse sectional vieW taken on the liney-jz/ of Figure 2,

Figure t is a. perspective vievv on an enlarged scale, showing one ofthe bearing bushes detached, and

Figure 5 is a perspective view, also on an enlarged scale Showing one ofthe bearing caps detached.

Referring to the drawings, the machine comprises a frame having membersa at the sides thereof, a portion only of one of the sides being shown,adapted to afford housings for bearings constituted, for example, bybushes b adapted to support the ends of the rotatable shaft c associatedWith the rollers d of the machine. Any desired number of rollers may beemployed, the vsaid rollers being arranged in any suitable manner,according to requirements. Themachine may, for examplefbe the usualstandard machine With thirteen or nineteen rollers, each of the shaftsof which 4would engage at each of the ends thereof, Vwith a bush Z).Each bush is detachably mounted Within its respective housing by meansof a detachable cap c, the caps being secured in position by means ofscrews f secured to the side members of the frame. The'housings and thecaps associated therewith are preferably providedV vvith linings c ofanti-friction metal or gun-metal, although any other suitable materialor materials may be employed, such linings surrounding, and engagingWith the bushes Which may each be enlarged or formed With a head orflange g bearing at the inner endthereof against the side of themachineframe, the said head or flange being shown tapered at It in anout- Ward direction. The bushes b are also preferably made ofanti-friction, or gun metal, but may be made of any other suitablematerial or materials. Y

Each of the bearings or bushes ZJ is of cylindrical formation and formedor provided With a lug or projection it which engages Within an openingor hole iin the corresponding cap e, see more particularly Figures-4 and5, the said lug or projection being shown as Vof circular formation andthe opening in the cap being made to accord therewith, the arrangementbeing such as to prevent rotation of the bearing or bush relatively tothe housing therefor and to the lining associated therewith. It' Will beunderstood that, alternatively, the said lug or projection L may beformed or provided on the said cap, the hole or opening i being in thebush g. Further, more than one lug or projection and correspondingopening may be provided, Whilst the formation thereof may be other thancircular.

An advantage gained by the present invention is that the lining e ismaintained intact and free from Wear by the bearing bush owing to thelatter not revolving in the lining.

With the improved bearing, when a shaft has to be removed or changed thecorresponding cap e is first detached and then the bush is slipped offthe shaft and applied .to the new shaft. Any Wear that has taken placebetween the shaft and the bush g can then be detected and rectified,land the adjustment, thereby made accurate. Again, a considerablereduction in the cost of fitting bearings and linings to machinery ofthe type above described is obtained by the adoption of the improvedconstructional form of bearing. Further, the bearing enclosed in thelining, When such bearing and lining are made of anti-friction materialor of gun metal, tends to keep the bearing in perfect alignment With theshaft and thus maintains the expense of relining down to a minimum. y

A further advantage gained by the use of machinery embodying theinvention, is that the hat material passing through the same is subjectto a gentle kneading action during its passage, the effect of Which isto facilitate the process, increase the output and to give a better feelor surface to the article being formed.

What I claim is:

In a felting machine a supporting frame Work, a plurality of bearingboxes mounted thereon in side by side relation, bearing box cap membersfor said boxes, each of said cap members having an aperture thereinsubstantially centrally thereof, said cap members being formed With arecess in each edge thereof intermediate the ends and a common securingmeans for fastening the adjacent sides of each pair of caps in positionon the frame Work, cylindrical one piece bearing members positionedWithin the boxes for longitudinal displacement and adapted to receivethe felting rolls of the felting machine, said bearing members beingprovided with cylindrical lugs intermediate the ends thereof adapt-ed tobe positioned in the aperture in the bearing caps to prevent rotativeand longitudinal movement of the bearing Within the box.

In testimony whereof I have hereunto signed my name.

GEORGE OLDHAM.
